From fbf0e452dc105b4aea2ddd4f90bc7cb19a870388 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 15 May 2012 17:28:53 -0700 Subject: [PATCH] staging: comedi: refactor ni_atmio16d driver and use module_comedi_driver Move the module_init/module_exit routines and the associated struct comedi_drive to the end of the source. This is more typical of how other drivers are written and removes the need for the forward declarations. Convert the driver to use the module_comedi_driver() macro which makes the code smaller and a bit simpler.
